HINGE.

SPECIFICATION forming part of Letters Patent No. 459,702, datedSeptember 15, 1.891.

Application filed December 19, 1890. Serial No. 375,265. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES A. FORSBERG, a citizen of the United States,residing at Rockford, in the county of Winnebago and State of Illinois,have invented certain new and useful Improvements in Hinges, of whichthe following is a specification.

The object of the invention is to construct a hinge for use inconnection with the front of a desk, so that the frame will be held insubstantially a horizontal position when open and permit it to beclosed.

In the accompanying drawings, Figure 1 is an isometrical representationof adisk, showing the style of front to which my improved hinge isapplicable. Fig. 2 is a side eleva tion of the hinge as seen from theinside. Fig. 3 is an isometrical representation of the dislg portion ofthe hinge as seen from its rear side. Fig. 4is an isometricalrepresentation of the pivotal portion of the hinge.

My improved hinge consists of two parts having a pivotal connection witheach other. The stationary part 1, or that part having a connection withthe main portion of the desk or structure, is of disk form, and has aprojection 2 extending from its face side. This disk is placed in arecess formed by boring the recess with a bit the required depth, andscrew-holes 3 receive screws which hold the disk in position. Ihave alsoformed the disk with radiating lugs 4, a reception for which is formedin the desk, and prongs 5 extend from the rear side of the disk, whichmay be driven into the wood. These lugs and prongs prevent the rotationof thedisk when pressure is brought to bear upon it. To the front of thedesk near its lower ends is inserted a bar 6, so as to be flush with itsface, and is of the disk attached thereto can be closed, as

shown at Fig. 1.

By constructing the disk 1 in circular form it can easily be applied tothe mainportion of the structure and is sure to fit, as the recesswithin which it is placed can be made with a bit having a diameter equalto the diameter of the disk, and an exact fit can be made in each case.

I claim as my invention- 1. A hinge consisting of a stationary Verticaldisk, a vertically-movable bar having connection therewith by means of ahorizontal pivot, and a projection extending horizontally from the faceof the disk to limit only the downward movement of the bar.

2. A hinge consisting of a stationary disk having radial projectionspreventing its rotation, a projection extending from its face, and a barhaving a pivotal connection with the disk and engaging the last-namedprojection when the hinge is open, substantially as set forth.
